Microbial Metabolites in Food Biotechnology

The term 'probiotic' was coined by the food industry to describe microbes beneficial to health. Scientific criticism based on poorly characterised isolates, soft clinical targets, and an absence of a mechanistic framework limited value of this concept. Current clinical and animal model studies support a role for certain 'probiotics', activating the common mucosal system through the stimulation of gut antigen-presenting cells to both promote protection and to switch regulatory mechanisms. It is concluded that a new term is required to identify bacteria that promote health through driving mucosal immune mechanisms, compared to those with strictly local effects. The term 'immunobiotics' is suggested as appropriate to fulfil this need.
